Working out factorial positive integer
Posted on 2003-11-20
i need to work out the factorial of a positive integer. ie the number multiplied by all the integers smaller than it down to 1. eg "5" = 5*4*3*2*1 = 120.
i also need to incorporate a test harness.
the code i have written works out teh factors of any given number but i am not sure off how to work out the final answer. ie. how to multiply them together.
#include<stdio.h>
void main (void){
int num,x;
void factorial(int);
printf("Please enter an integer: ");
scanf("%d", &num);
fflush(stdin);
for(x=1; x<num; x++)
factorial (x);
}
void factorial (int x){
printf("x = %d\n", x);
help would b much appreciated. cheers.
